Rectal mucosal dissection commencing directly on the anorectal line versus commencing above the dentate line in laparoscopy-assisted transanal pull-through for Hirschsprung's disease: Prospective medium-term follow-up.

BACKGROUND In 2007, we began using the anorectal line (ARL) as the landmark for commencing rectal mucosal dissection (RMD) instead of the dentate line (DL) during laparoscopy-assisted transanal pull-through (L-TAPT) for Hirschsprungs disease (HD). We conducted a medium-term prospective comparison of postoperative fecal continence (POFC) between DL and ARL cases to follow our short-term study. METHODS POFC is assessed by scoring frequency of motions, severity of staining, severity of perianal erosions, anal shape, requirement for medications, sensation of rectal fullness, and ability to distinguish flatus from stool on a scale of 0 to 2 (maximum: 14). RESULTS Patient demographics were similar for ARL (2007-2014: n=33) and DL (1997-2006: n=41). There were no intraoperative complications and 2 cases of postoperative colitis in both ARL (6.1%) and DL (4.9%). Mean annual medium-term POFC scores for the 4-7 term of this study were consistently better in ARL: 9.7±1.4*, 10.1±1.6*, 10.6±1.6, and 11.3±1.4* in ARL and 8.6±1.5, 9.1±1.6, 9.8±1.9, 10.0±1.6 in DL (*: p<0.05). CONCLUSIONS Medium-term POFC is better when the ARL is used as the landmark for RMD during L-TAPT for HD.

Comparison of outcomes between laparoscopy-assisted and posterior sagittal anorectoplasties for male imperforate anus with recto-bulbar fistula

PURPOSE All reports comparing laparoscopy-assisted anorectoplasty (LAARP) with posterior sagittal anorectoplasty (PSARP) in male high-type imperforate anus include a mix of recto-vesical, recto-prostatic, recto-bulbar, and absent fistula cases without focusing on recto-bulbar fistula (RBF), the most challenging type to treat laparoscopically. We compared LAARP with PSARP for treating only RBF. METHOD We used our fecal continence evaluation questionnaire (FCE; maximum score=10), scoring of magnetic resonance imaging (MRI) findings (MRI scores), and the angle between the rectum and the anal canal (RAA) to assess 20 RBF cases (LAARP=12, PSARP=8) treated from 2000 to 2013 prospectively. RESULTS Mean ages at surgery, MRI scores, mean RAA, and duration of raised C-reactive protein (6.6 vs. 6.7days; p=NS) were similar. In all cases, postoperative MRI showed no residual fistula and normal urination. LAARP had consistently higher FCE (7.9 vs. 7.8 at 3years; 8.6 vs. 8.3 at 5years; 8.9 vs 8.6 at 7years; p=NS, respectively), less wound infections (0 vs. 37.5%; p<0.05), higher incidence of rectal mucosal prolapse (50.0 vs. 0%; p<0.05), and required less analgesia (p<0.05). CONCLUSION Although LAARP and PSARP are comparable for treating RBF, LAARP is associated with less wound infections and higher incidence of rectal mucosal prolapse.

Pulmonary lobectomy techniques in infants and children

Thoracoscopic pulmonary lobectomy (TPL) techniques in infants and children are presented practically with concise descriptions and numerous illustrations. TPL is the treatment of choice for congenital pulmonary airway malformation and intralobar pulmonary sequestration, both now commonly diagnosed prenatally. Timing of surgery is somewhat controversial in asymptomatic cases with small isolated lesions. Incomplete fissures and history of chest infections are most problematic. Thorough understanding of anatomic relations preoperatively is vital for successful outcome and thin-slice computed tomography with 3D reconstruction of vessels is valuable. Judicious placement of trocars and switching instruments between trocars improves visualization and safety. Specific techniques for all commonly performed TPL are included.

Liver transplantation for deterioration in native liver function after portoenterostomy for biliary atresia in Japan: Short- versus long-term survivors

PURPOSE We reviewed our post-Kasai portoenterostomy biliary atresia (BA) patients who required liver transplantation (LTx) for deterioration in native liver (NL) function to investigate mortality in relation to age at LTx. METHODS BA patients indicated for LTx when less than 18years old (U18; n=17) and when 18 or older (18+; n=13) were compared. All achieved jaundice clearance postoperatively (TBil ≤1.2mg/dL (≈20μmol/L)). RESULTS In U18, living-donor (LD) LTxs were performed at a median of 6.1years (range: 0.5-16.7; n=14) and cadaveric (CD) LTxs at a median of 1.3years (1.1-1.5; n=3). In 18+, LDLTxs were performed at a median of 28years (18-37; n=8), and 1 case died from graft versus host disease. CDLTxs were indicated in 5, but 4 died at a median of 30years (26-32), a mean of 1.4years (0.7-1.8) after NL deterioration commenced. One case is awaiting CDLTx. At the time of review, all U18 and 7 LDLTx cases in 18+ were clinically stable. Mortality rates were 0% in U18 and 38% in 18+ (P=.006). CONCLUSION Our results highlight the extremely grave prognosis for long-term BA patients requiring LTx when 18 or older because of poor donor availability in Japan. LEVEL OF EVIDENCE Level III.
